Answer
6.9 x 10¹²Hz
Explanation:
Given parameters:
Wavelength of the wave = 4.35 x 10⁻⁵m
Unknown:
Frequency of the wave = ?
Solution:
The speed of a wave is related to the wavelength and frequency using the expression below;
C = Fλ
C is the speed of light = 3 x 10⁸m/s
F is the frequency
λ is the wavelength
Insert the given parameters and solve;
3 x 10⁸ = F x 4.35 x 10⁻⁵
F =
= 6.9 x 10¹²Hz
They have a mass for the particles
There are no totally elastic collisions
There are intermolecular forces

Answer:
100L of N2
Explanation:
First let us obtain the number of mole of NH3 that occupied 200L at stp. This can be achieved by doing the following:
1mole of NH3 occupied 22.4L at stp.
Therefore, Xmol mole of NH3 will occupy 200L i.e
Xmol of NH3 = 200/22.4 = 8.93moles.
Now let us generate a balanced equation for the reaction.
N2 + 3H2 —> 2NH3
From the equation above,
1mole of N2 produced 2moles of NH3.
Therefore, Xmol of N2 will produce 8.93moles of NH3 i.e
Xmol of N2 = 8.93/2 = 4.47moles
Now let us convert 4.47moles to N2 to Litres. This is illustrated below:
1mole of N2 occupied 22.4L at stp
Therefore, 4.47moles of N2 will occupy = 4.47 x 22.4 = 100L
Therefore, 100L of N2 is used in the reaction
